Volunteers take the pulse of Farm Aid

Volunteerism is the backbone of this event today. And SERVE 60, a national volunteer initiative based out of Milwaukee, has brought more than 30 people together here to find out how to make the next Farm Aid even better. They're surveying Farm Aid visitors asking about their musical and eating habits and preferences.

The SERVE 60 folks are following the idea of service, which is an idea that appeals to such volunteers as Karla "With a K" Iseler of Milwaukee, whose grandfather was a beekeeper and whose father bribed her to pick rocks out of his garden at a nickel a stone.

"I feel very connected to people getting their hands in the dirt. The more people are removed from the land the worse off we are," she said.
